values-sw600dp won't work

Question

I have the following values folders (in addition to the default one): values-sw400dp, values-sw600dp. Since I need so remove spacing between my actionBar icons I used a style:

     <style name="ActionBarTabStyle" parent="@android:style/Widget.Holo.ActionBar.TabView">
    <item name="android:background">@android:color/transparent</item>
    <item name="android:paddingLeft">0dp</item>
    <item name="android:paddingRight">0dp</item>
</style>

and just copied styles.xml into all of the values folders. On SGS2 i9100 running 4.1.1 it works fine, but on a PocketBook tablet (running same android version) the spacing seems to be the default one. The following method returns 600:

    public static int getScreenWidth(Activity a) {

    Display display = a.getWindowManager().getDefaultDisplay();
    DisplayMetrics outMetrics = new DisplayMetrics();
    display.getMetrics(outMetrics);

    float density = a.getResources().getDisplayMetrics().density;
    float dpWidth = outMetrics.widthPixels / density;

    return (int) dpWidth;

}

So the question is: why does the device ignore styles from values-sw600dp folder?

UPDATE I just added windowBackground item to styles in values-sw600dp. It is displayed correctly. But why is the padding for the actionBar ignored? Setting negative padding does not change anything

Answer 1

Try this to set paddings to your actionbar icons:

<style name="AppTheme" parent="Theme.Sherlock">
    <item name="actionButtonStyle">@style/MyActionButtonStyle</item>
    <item name="android:actionButtonStyle">@style/MyActionButtonStyle</item>
</style>

<style name="MyActionButtonStyle" parent="Widget.Sherlock.ActionButton">
    <item name="android:minWidth">32dip</item>
    <item name="android:padding">0dip</item>
</style>

The default value of android:minWidth for the ActionBar buttons is 56dip. Don't forget to set @style/AppTheme as the Activity's theme.
